Diverter ball valve made of stainless steel with threaded connections

The optimal design of the flow channels within the diverter ball valve enable particularly high flow rates. This significantly reduces flow pressure losses to the safety valves and safe operation remains ensured.
The use of 1.4404 and 1.4408 high-alloy stainless steels enables high resistance against internal and external influences.
For the use with gases that are in contact with food an FDA-compliant sealing material has been used. Thanks to the oil- and grease-free manufacturing process, the diverter ball valves are suitable for use in systems using oxygen. With the ergonomically shaped handle and the separate testing connections, the diverter ball valve is optimally prepared for the maintenance of the safety valves.

Diverter ball valve for the installation of for example two safety valves in combination with bursting discs for the protection of containers designed for the storage of cryogenic gases. The requirements of the PED relating to redundant or diverse safety devices are fulfi lled by this fi tting in combination with safety valves of the 2400 series. On each side two additional connections for bursting discs are available.
In case the safety valves need to be maintained or the bursting discs replaced, the side requiring maintenance can be shut off.

  • For the storage of cryogenic liquifi ed gases, such as LIN, LOX, LAr, CO2, LNG.
  • N2 in pharmaceutical / foodstuffs applications
  • O2 for medical supply equipment
  • CO2 for foodstuffs/ industrial applications
  • LAr for welding
  • Cooling plants
